Stabilizing plasma in fusion reactors brings us a step closer to creating an unlimited source of energy.
. If we talk about our typical situations on earth, plasma does not qualify as a liquid, solid, or gas matter. In the universe, it is found in abundance in stars.
More often than not, plasma is found oscillating in density and temperatures, and due to this, there is generally a halt in the nuclear fusion reaction — a process called sawtooth instability which occurs when the current becomes strong enough to destabilize and halt the reactions. To keep the current in the core of the plasma, the reactor makes use of a magnetic flux pumping mechanism. This also keeps some of the plasmas stable to keep the reactions going rather than halting it.
In the PPPL simulations, the flux pumping was developed with a hybrid scenario where the current remains flat in the plasma core and the pressure of the plasma is sufficiently high. The combination results in a ‘quasi-interchange mode’ that mixes up the plasma while deforming the magnetic field.
